As long as in addition, connection publisher server 1 and the network publisher server 1 of reproduction client 2 and reproduction 2 energy of client
The network of content is enough transmitted and received, is not particularly limited.For example, as above-mentioned network, radio network can be both applied, also may be used
To apply internet.In addition it is also possible to using and with multiple networks such as internet and radio network hybrid network.
Publisher server 1 be issue content device, the server controls of the function including being uniformly controlled publisher server 1
Portion 10, the server storage section 11 for being stored in the data used in publisher server 1 and publisher server 1 are used for and outside
The server communication portion 12 that device communicates.In addition, server controller 10 includes component transformation component 13, configuration information is analyzed
Portion's (acquiring unit) 14, configuration information generating unit (configuration information generation unit) 15 and issue control unit (issue control unit)
16, configuration information 17 and content 18 are stored in server storage section 11.
Content 18 with defined segmentation unit is split and is transformed to the component of issue by component transformation component 13.Separately
Outside, it is stored as the component of issue in content 18, component transformation component 13 can also be omitted.
Configuration information analysis portion 14 obtains/analyzes the configuration information 17 stored in server storage section 11, and determine by
Which of information included in configuration information 17 is set to main configuration information (with reference to form configuration information), which is set
For secondary configuration information (reference object configuration information).In addition, the details of main configuration information and secondary configuration information is detailed afterwards
Explanation.
Configuration information generating unit 15 generates main configuration information and secondary composition according to the decision of configuration information analysis portion 14
Information.The main characteristic point of publisher server 1 is, main configuration information and secondary configuration information are generated from configuration information 17,
And these information are issued.
Issue the issue of 16 control content 18 of control unit.Specifically, issue control unit 16 and determine that component transformation component 13 is given birth to
Into the main configuration information that generates of component and configuration information generating unit 15 and secondary configuration information issuing time table.Also,
According to the issuing time table determined, via server communication portion 12, by component, main configuration information and secondary configuration information issue
To reproduction client 2.
Configuration information 17 be represent the component of constitution content 18, the display location of the component, size etc. layout or can
The information of the reproducing condition (playback system) of combination etc..Configuration information 17 can also be the information for example shown in Figure 16 (b).Separately
Outside, represent the state that configuration information 17 and content 18 are stored separately in Fig. 1, but configuration information 17 can also with content 18
The state of multiplexing stores.
Content 18 is the content that publisher server 1 is issued.Content 18 is made of multiple components, with defined segmentation unit point
It cuts, is issued as the transmission packe that attached head.In addition, the component as constitution content 18, such as enumerate live image, sound
Sound, text, program etc..
On the other hand, it is reception content and the device reproduced to reproduce client 2, reproduces client 2 including being uniformly controlled
The client control unit 20 of function is stored in and reproduces the client storage part 21 of data that is used in client 2 and for again
The client communication portion 22 that existing client 2 communicates with external device.In addition, client control unit 20 includes reproducing control
Portion 23 and reproducing unit 24, are stored with configuration information 25 in client storage part 21, and are provided with reception data store
26。
Reproducing control portion 23 is uniformly controlled the reproduction of content 18.Specifically, publisher server 1 is sent out in reproducing control portion 23
The main configuration information of cloth and secondary configuration information are analyzed, and reproducing unit 24 is made to reproduce content 18 based on the analysis result.This
Outside, the main configuration information received and secondary configuration information are recorded in client by reproducing control portion 23 as configuration information 25
In storage part 21, when reproducing content 18 suitably with the information.
Reproducing unit 24 reproduces content 18 according to the control in reproducing control portion 23.More specifically, reproducing unit 24 will be formed
The component of content 18 is reproduced by corresponding to the playback system of its attribute.For example, if the component of reproduced objects is live image
Or sound, then it is rendered, and is exported from display unit (not shown) and audio output unit.In addition, do not scheming then if text
It shows in the display unit shown, is then performed if program.Certainly, reproduction, display, the execution processing corresponding to component can also
It is performed respectively in different blocks.
《The example 1 of configuration information》
Illustrate the configuration information of the generation of publisher server 1 based on Fig. 2.Fig. 2 is to represent that the configuration information that will be stored 17 divides
The figure of an example for the configuration information for being segmented into main configuration information and 2 secondary configuration informations and generating.In addition, as segmentation basis
Configuration information 17 is the configuration information shown in Figure 16 (b).
In the main configuration information (main) of same figure, the version that description has configuration information is " 1 ".In addition, pass through ＜
Components ＞ labels, the component of constitution content are described in the form of the reference of ＜ comp href=" " ＞.In addition, pass through
＜ compositions ＞ labels, the playback system of component are described in the form of the reference of ＜ par href=" " ＞.
In this way, main configuration information is the knot being rewritten as a part for the information included in configuration information 17 with reference to form
Structure, for representing the whole summary of the composition of content.Due to being rewritten as a part for information with reference to form, so and Figure 16
(b) configuration information is compared, and data volume is significantly cut down.
Also, since the component of constitution content and its playback system with reference in the form of to describe, so wanting change
In the case of the component of constitution content and its playback system, main configuration information need not be changed.Therefore, it is necessary to main configuration informations
Newer frequency it is also lower than the configuration information of Figure 16 (b).
On the other hand, in secondary configuration information (sub), including become the reference from main configuration information object it is specific
Information (in the information included in configuration information 17, is rewritten as the information with reference to form) in main configuration information.That is, compared with
Main configuration information represents the whole summary of the composition of content, and secondary configuration information is for details of the expression on a part for content.
That is, in the secondary configuration information of same figure, in version in the secondary configuration information of " 1 ", description has definite c1 to c4's
The information of component is assigned these components the id of " s1 ".That is, ＜ comp href=" sub#s1 "/＞ tables of main configuration information
Show the component with reference to the id=s1 in secondary configuration information.
In addition, in version in the secondary configuration information of " 1 ", description has while reproduces as the c1 of video component and as sound
The c2 of frequency component.Which can be selected and used in addition, c3 and the c4 description as text component have.Also, to these
Playback system is assigned the id of " p1 ".That is, the ＜ par href=" sub#p1 " of main configuration information/＞ represents to believe with reference to secondary form
The playback system of id=p1 in breath.
Thereby, it is possible to the situation with having used the configuration information shown in Figure 16 (b) in the same manner, while reproduce c1's and c2
Component in the reproduction, uses the component of c3 or c4 as needed.
In addition, in version in the secondary configuration information (different editions reference object configuration information) of " 2 ", also description has id=
The component of s1 and the playback system of id=p1.But in version in the secondary configuration information of " 2 ", description content is " 1 " with version
Secondary configuration information it is different.
Specifically, in version in the secondary configuration information of " 2 ", description has the component of c5 to c8.In addition, description has simultaneously
Reproduce the c5 as the video component and c6 as audio component, also, the c7 and c8 as text component describe that have can
Which is selected and is used.
Thereby, it is possible to the situation with having used the configuration information shown in Figure 16 (b) in the same manner, while reproduce c5's and c6
Component in the reproduction, uses the component of c7 or c8 as needed.
In this way, in the present embodiment, by referring to main configuration information and secondary configuration information, can carry out and use with
Identical reproduction during past configuration information.In addition, details is described below, but believe will form based on a configuration information segmentation
In the case of breath and secondary configuration information, the issue frequency for the main configuration information for needing newer frequency low can be reduced.As a result, with
It is compared when configuration information 17 is issued as former state, additionally it is possible to cut down issue data volume as a whole.
In addition, be set to be not particularly limited with reference to the part of form in configuration information 17, but can also will such as ＜
Any one in the playback system in component and ＜ compositions ＞ labels in components ＞ labels is set to join
According to form.In addition it is also possible to a part of component in such as ＜ components ＞ labels is set to reference form, similarly,
A part for playback system in ＜ compositions ＞ labels can also be set to reference to form.
＜ published methods ＞
Then, the published method of above-mentioned main configuration information and secondary configuration information is illustrated based on Fig. 3.Fig. 3 is to represent main
The figure of an example of the issue timing of configuration information and secondary configuration information.In addition, in figure 3, it also with Figure 16 (a) in the same manner, will
One-component, a configuration information are expressed as a block, and the block of dotted line represents arbitrarily used component.
In the example in fig. 3, the issue timing of component is also identical with the example of Figure 16 (a), first, issues the component of c1 to c4,
Afterwards, the component of c5 to c8 is issued.More specifically, the t0 at the time of issue start time as reproduced objects content, is opened
The issue of the component of beginning c1 to c4.Also, the t3 at the time of composition as reproduced objects content changes the moment, starts c5 to c8
Component issue.
On the other hand, the published method of configuration information and the example of Figure 16 (a) are different.I.e., in the example in fig. 3, moment t0,
T3, t5 issue main configuration information (main), and configuration information (CI) of the issue frequency than Figure 16 (a) is low.
In addition, in the example in fig. 3, at the time of the component of c1 to c4 is issued during t0 to t3, repeat issue include with
By the secondary configuration information of the version 1 of the related information of the component during being set to reproduce during this period.The issue frequency of secondary configuration information
It is higher than main configuration information.
Similarly, at the time of the component of c5 to c8 is issued during t3 to t5, repeating issue is included with that will set during this period
For the secondary configuration information of the version 2 of the related information of the component during reproduction.
In the case where component, main configuration information and secondary configuration information are issued in such timing, 2 energy of client is reproduced
Enough timings in the both sides for obtaining main configuration information and secondary configuration information start the reproduction of component.
For example, t1 has started in the case of receiving at the time of same figure, since the moment is the version 1 of the 2nd issue
In the issue way of secondary configuration information, so reproducing the finishing receiving until the secondary configuration information of version 1 then issued of client 2
At the time of t2 until become etc. state to be reproduced.
Here, in the feelings for reproducing client 2 and passing by (before moment t0 (not shown)) and receiving from publisher server 1 content
Under condition, main configuration information is prestored by reproducing client 2, in moment t2, using the main configuration information received in the past and
In the secondary configuration information for the version 1 that moment t2 is finished receiving, can since moment t2 component c1 to c4 reproduction.
Also, due in moment t3, starting the issue of the secondary configuration information of component c5 to c8 and version 2, in moment t4,
The secondary configuration information of version 2 finishes receiving, so after moment t4, can also carry out the reproduction of component c5 to c8.
As long as in addition, main configuration information and secondary configuration information the reproduction corresponding to desired beginning component c1, c2 when
The timing issue at quarter.For example, wanting since moment t0 in the case of reproduction, as long as finishing receiving that in such as moment t0
Main configuration information and secondary configuration information are issued in the timing of sample.
On the other hand, in the case of moment t2 in the past no main configuration information of reception, until the main composition then issued
Information at the time of finishing receiving until t4 become etc. state to be reproduced.Also, obtain main structure due to becoming in moment t4
Into information and the state of the both sides of secondary configuration information, so as to starting the reproduction of component c1 to c4 based on these information.
In addition, in the secondary configuration information of moment t4, also acquisition version 2, but due to described in the secondary configuration information in version 2
There is the information related with component c5 to c8 (with reference to Fig. 2), so cannot be utilized in the reproduction of component c1 to c4.Therefore, reference
Receive before a time t 3, description has the secondary configuration information of the version 1 of the information related with component c1 to c4 and reproduces.
＜ is on the identification ＞ for using payload grade
In the case where using main configuration information described above and secondary configuration information, reproducing client needs to identify and form
The configuration information that each component of content is multiplexed and issues together is main configuration information or secondary configuration information.Certainly, by structure
Content into information is analyzed, and can be carried out the identification of main configuration information or secondary configuration information, but obtained quilt every time
Waste is more if its analysis is carried out during the configuration information repeatedly issued.
Here, main configuration information and secondary configuration information identically with each component of constitution content, with payload unit
It is multiplexed and is issued.Accordingly, it is desirable to main configuration information or secondary configuration information are identified using payload grade,
Furthermore it is possible to identify its version.This is because thus without in order to which these are identified and analyze configuration information.
Here, illustrate to be used for the example for identifying the information of configuration information described in the head of payload based on Fig. 4.Fig. 4 is
It represents to describe in the head of payload of main configuration information, secondary configuration information and two components is issued and be formed for identifying
The figure of an example of the data structure of the information of information.
In the example of diagram, main configuration information (main) and secondary configuration information (sub) are not divided and are respectively stored in
In one payload, component c1 and component c2 are divided into multiple portions and are respectively stored in individual payload.This
Outside, main configuration information (main) and secondary configuration information (sub) repeat to be stored in multiple payloads so that are repeated hair
Cloth.
Also, in the payload head of main configuration information, described in the form of " Payload Type=CI " effective
The content of load is configuration information, and represents in the form of " ID=main " to be stored in the payload and main formed letter
Breath.In addition, description has the version of the main configuration information in the form of " Ver=(version number) ".
Similarly, in the payload head of secondary configuration information, describe to have in the form of " Payload Type=CI "
The content of effect load is configuration information, and represents that pair is stored in the payload is formed letter in the form of " ID=sub "
Breath.In addition, description has the version of the pair configuration information in the form of " Ver=(version number) ".
Client 2 is reproduced by referring to these information described in payload head, need not be analyzed in payload
Data, it becomes possible to identify that stored in the payload is which of main configuration information, secondary configuration information configuration information.
As a result, in the wait reception state of main configuration information or secondary configuration information, it can successfully determine to receive etc. to be received
Configuration information.
In addition, reference only to payload head, it becomes possible to identify the version of the configuration information received, thereby, it is possible to suitable
It determines to receive over without the configuration information of the version received sharply.
In addition, for identifying that the information of main configuration information and secondary configuration information may not be by only referring to effectively negative
Carrier head and the information that can determine the identifier of main configuration information or secondary configuration information.Due to configuration information classification based on form
Information, secondary configuration information so for example in payload head, only description can also indicate whether to compare for the 1 of main configuration information
Special mark, can cut down the information content described in payload head.In addition, at this point, as needed, the knowledge of each configuration information
Not Fu can also for example the inside of configuration information with<Ci id=" sub ">…</ci>Such form description.
In addition, can also be set to represent to whether there is the mark of 1 bit of change using the version management of payload grade, it is real
The version number on border can also analyze configuration information to determine.At this point, shown in the bit change when, receive start when and
After Fault recovery is received, analyze the configuration information in actually active load and confirm more new content.
《The example 2 of configuration information》
In above-mentioned, illustrate and a configuration information is divided into a main configuration information and a secondary configuration information, it will
Secondary configuration information generates the example of multiple versions, but can also further split secondary configuration information according to component.Thereby, it is possible to
Further cut down transmitted data amount.
Here, the configuration information for further splitting secondary configuration information according to component is illustrated based on Fig. 5.Fig. 5 is to represent
Configuration information 17 is split to the figure of an example of the configuration information generated for main configuration information and 4 secondary configuration informations.In addition, into
Configuration information 17 for the basis of segmentation is the configuration information shown in Figure 16 (b).
In the ＜ components ＞ labels of the main configuration information of Fig. 5, also identically with the example of Fig. 2, constitution content 18
Component described by with reference in the form of, but the difference from the example of Fig. 2 is, referenced component become " sub1#s1 " and "
Two of sub2#s2 "." sub1 " is somebody's turn to do as the first secondary configuration information (reference object configuration information), " sub2 " is the second secondary composition
Information (secondary reference object configuration information).
In addition, in the ＜ compositions ＞ labels of the main configuration information of Fig. 5, the playback system of component is to quote shape
Formula describes.Specifically, as playback system, " sub1#p1 " is described with reform, and uses optional point
Reference object during amount is described as " sub2#e2 ".
Also, in the figure, the first secondary configuration information (sub1) and the second secondary configuration information (sub2) are illustrated respectively
Two versions (1 and 2).
Specifically, in the first secondary configuration information (version 1), description has the component of c1 and c2, to these components point
The id of " s1 " is matched somebody with somebody.In addition, description has while reproduces the c1 as video component and the c2 as audio component, to the reproduction side
Formula is assigned with the id of " p1 ".
In addition, in the second secondary configuration information (version 1), description has the component of c3 and c4, these components are assigned with "
The id of s2 ".In addition, description has which of c3, c4 used as text component, which is assigned with " e2 "
id。
Therefore, by referring to main configuration information, the first secondary configuration information (version 1) and the second secondary configuration information (version
1) identical reproduction when, can carry out with having used the configuration information shown in Figure 16 (b).
That is, by referring to the description of ＜ components ＞ labels of main configuration information, the first secondary configuration information (version 1)
Id=s1 description and the second secondary configuration information (version 1) id=s2 description, can determine reproduced objects for c1 extremely
4 components of c4.
Also, by referring to the description of the ＜ compositions ＞ labels of main configuration information, the first secondary configuration information (version
The description of the id=e2 of the description of this id=p1 1) and the second secondary configuration information (version 1), can reproduce simultaneously c1 and
The component of c2 in the reproduction, uses the component of c3 or c4 as needed.Certainly, even if not obtaining and arbitrarily reproducing
The second related secondary configuration information of component, as long as obtaining the first secondary configuration information, it becomes possible to reproduce the component of c1 and c2.
Similarly, in the first secondary configuration information (version 2), description has the component of c5 and c6, these components are distributed
The id of " s1 ".In addition, description has while reproduces the c5 as video component and the c6 as audio component, to the playback system
It is assigned with the id of " p1 ".
Also, in the second secondary configuration information (version 2), description has the component of c7 and c8, these components are assigned with "
The id of s2 ".In addition, description has which of c7, c8 used as text component, which is assigned with " e2 "
id。
Therefore, in the case of the first and second secondary configuration information with reference to version 2, it is c5 to c8 to determine reproduced objects
4 components.Furthermore it is possible to reproduce the component of c5 and c6 simultaneously, in the reproduction, as needed, use c7's or c8
Component.Certainly, even if not obtaining the secondary configuration information of second related with the component arbitrarily reproduced, believe as long as obtaining the first secondary form
Breath, it becomes possible to reproduce the component of c1 and c2.
In this way, it is described by the component that must be reproduced (c1, c2, c5, c6) and the component (c3, c4, c7, c8) arbitrarily used
In the case of in different secondary configuration informations, even if by reducing newer frequency, the second secondary structure that problem can also be lacked
Into the issue frequency of information, as a whole, additionally it is possible to cut down issue data volume.
＜ published methods ＞
Then, the published method of above-mentioned main configuration information and secondary configuration information is illustrated based on Fig. 6.Fig. 6 is to represent main
The figure of an example of the issue timing of configuration information and 4 secondary configuration informations.In addition, in figure 6, also with Figure 16 (a) and Fig. 3
In the same manner, one-component, a configuration information are expressed as a block, the block of dotted line represents the component arbitrarily used.
In the example of Fig. 6, the issue timing of component is also identical with the example of Fig. 3, starts the component of c1 to c4 in moment t0
Issue, starts the issue of the component of c5 to c8 in moment t3.In addition, the issue timing of main configuration information is also identical with the example of Fig. 3.
On the other hand, the published method of secondary configuration information and the example of Fig. 3 are different.That is, in the example of Fig. 6, issue first is secondary
Configuration information (sub1) and 2 kinds of secondary configuration informations of the second secondary configuration information (sub2).In addition, during moment t0 to t3
The version of the secondary configuration information of issue is all 1, and the version for the secondary configuration information issued during moment t3 to t5 is all 2.
Also, the issue frequency of the first secondary configuration information is identical with the secondary configuration information of Fig. 3, but the second secondary configuration information
It is lower than the first secondary configuration information to issue frequency.As a result, compared with the example of Fig. 3, the data volume of the secondary configuration information of issue is cut in.
In the case where being reproduced with reference to such main configuration information and 4 secondary configuration informations, reproduce in client 2
Processing for example as follows.
That is, in the case where moment t1 has started to receive, since the moment is the first secondary structure of the version 1 of the 2nd issue
Into in the issue way of information, so reproducing client finishing receiving until the first of version 1 the secondary configuration information for then issuing
At the time of t2 until become etc. state to be reproduced.
Here, in the case where moment t2 receives main configuration information in the past, by using the main composition received in the past
Information and the first secondary configuration information in the moment t2 versions 1 finished receiving, can since moment t2 component c1 and c2
It reproduces.
In addition, at this point, by using the version 1 finished receiving in moment t6 the second secondary configuration information, can be from the moment
T6 starts the use of component c3 and c4.Since component c3 and c4 are not required the text of the subtitle used, if so should
The delay (t2 to t6) of degree in example, then it is assumed that most users can allow.
Also, the issue of the due in moment t3, starting version 2 first and second secondary configuration information, in moment t4, this
It finishes receiving, so after moment t4, can also carry out the reproduction of component c5 to c8.
On the other hand, in moment t2 in the case of past no main configuration information of reception, until the main structure then issued
Into information at the time of finishing receiving until t4 become etc. state to be reproduced.Also, obtain master due to becoming in moment t4
Whole states of the pair configuration information of configuration information, first and second, institute based on these information so as to start component c1
To the reproduction of c4.
As previously discussed, in the example of Fig. 6, according to the height of the importance of each component (whether require instant playback or
Whether person must reproduce) come component of classifying, generation corresponds to the secondary configuration information of each classification.Also, in these secondary configuration informations
In, the issue frequency of the relatively high secondary configuration information of importance is improved, reduces the issue of the relatively low secondary configuration information of importance
Frequency.
Specifically, on for reproduce the high AV components of the necessity that must reproduce and reproduce immediately (video component with
And audio component) the first secondary configuration information, issued with frequent.On the other hand, arbitrarily used and i.e. on for using
Second secondary configuration information of the text component of the relatively low subtitle of the necessity of Shi Zaixian etc. is issued with low-frequency degree.
Thereby, it is possible to by the first secondary configuration information etc. the reproductions of caused AV components to be received start delay and be suppressed to
Min., and the issue data volume as configuration information entirety can be cut down.
Alternatively, it is also possible to the dissemination method according to component, change to reproduce the issue frequency of the configuration information of the component.
For example, as the data broadcasting used in existing digital broadcasting, component slides (Carousel) and repeats to send in itself
In the case of, it can also be coordinated to issue frequency and send the configuration information related with the component.
《The example 3 of configuration information》
In above-mentioned, the letter for the combination that the component reproduced simultaneously will be represented as the information for representing playback system is illustrated
Breath describes the example in secondary configuration information, but can also describe to represent the information of layout.
Here, the example using the secondary configuration information for describing the information for representing layout is illustrated based on Fig. 7 and Fig. 8.Fig. 7 is
Represent the figure of an example of the layout of component, Fig. 8 is an example for representing the configuration information for carrying out rendering components with the layout of Fig. 7
Figure.
In the example of Fig. 7,3 groups of layouts of " layout1 " extremely " layout3 " become the object of user's selection.Rendering components
User select desired layout from these layouts, reproduce client 2 and component shown according to selected layout.
Specifically, in the case where having selected layout1, first, using the picture layout of acquiescence.The screen cloth of acquiescence
Office refers to, v1 (video component) is set to full frame shows, v2 (video component) is set to small picture shows and reproduce a1 (audios
Component).
Afterwards, the timing of defined time is being have passed through, is being laid out automatic change.Layout after change refers to, v2 is set to
Full frame, which shows, v1 is set to small picture shows and reproduces a1.Also, in the timing further across the defined time, cloth
Office automatically returns to acquiescence.
On the other hand, it is automatic without what is be laid out described above in the case where having selected layout2 or layout3
Change, maintains selected layout.That is, in the case where having selected layout2, v1 is set to full frame and shows, be set to v2
Small picture shows and reproduces a1.In addition, in the case where having selected layout3, v2 is set to full frame and shows, v1 is set to small
Picture shows and reproduces a1.
It can be realized using the display of such layout by the configuration information of Fig. 8.The configuration information of Fig. 8 includes main structure
Into information, the first secondary configuration information, the second secondary configuration information, include three versions of version 1 to 3 in the second secondary configuration information
This.
In the main configuration information of same figure, by ＜ components ＞ labels, with reference to the component attribute of " sub1#s1 ".
It in addition, by ＜ layouts ＞ labels, defines " reg_1 " shown corresponding to full frame and is shown corresponding to small picture "
reg_2"。
Also, by ＜ compositions ＞ labels, description have with " sub2#layout1 " of outer non-economic, "
Layout2 " and " which of layout3 " layout reproduces.In addition, description has the specific interior of these layouts respectively
Hold.
On the other hand, in the first secondary configuration information, description has the component of " v1 ", " v2 " and " a1 ", to these components
It is assigned with the id of " s1 ".
In addition, in the version 1 of the second secondary configuration information, description has shows video component v1, in reg_2 in reg_1
The layout of middle display video component v2 and the a1 for reproducing audio component.Also, the id of " layout1 " is assigned with to the layout.
Similarly, in the version 2 of the second secondary configuration information, description has shows video component v1, in reg_ in reg_2
Video component v2 is shown in 1 and reproduces the layout of audio component a1.Also, the id of " layout1 " is assigned with to the layout.
In addition, in the version 3 of the second secondary configuration information, identically with version 1, description has shows video in reg_1
Component v1, video component v2 is shown in reg_2 and reproduces the layout of audio component a1.Also, the layout is assigned with "
The id of layout1 ".
It, can by obtaining main configuration information and the first secondary configuration information in the case of configuration information more than using
Reproduce the component of v1, v2, a1.Additionally it is possible to make any of user in arbitrary timing selection layout1 to layout3
It is a, and according to selected layout come rendering components.Even that is, in the case of the secondary configuration information of no reception second,
It can be reproduced according to the layout described in main configuration information.
Also, in the case where having selected layout1, by the secondary configuration information of timing acquisition second for changing the layout
Version 2, as shown in fig. 7, can automatically (no user operation) change layout.This is because in the " sub2# of main configuration information
The information change of reference is the second secondary configuration information of version 2 in layout1 ".When the layout is automatically returned to original
It is identical, in the version 3 of the secondary configuration information of the timing acquisition second of change layout.
＜ published methods ＞
Then, the published method of above-mentioned main configuration information and secondary configuration information is illustrated based on Fig. 9.Fig. 9 is to represent main
The figure of an example of the issue timing of configuration information and secondary configuration information.In addition, in fig.9, also identically with Fig. 3 and Fig. 6,
One-component, a configuration information are expressed as a block.
In the example of Fig. 9, the t0 at the time of issue start time as reproduced objects content, component a1, v2, v1 start
Issue.In addition, in moment t0, the second secondary configuration information of main configuration information, the first of version 1 the secondary configuration information and version 1
Start to issue.
In addition, the issue timing of main configuration information is identical with the example of Fig. 3, Fig. 6, when the issue of corresponding component starts only
Issue 1 time.In addition, the issue timing of the first secondary configuration information is identical with the example of Fig. 6, with defined week during component is issued
Phase repeats to issue.On the other hand, on the second secondary configuration information, the different information of a version is respectively issued.
Here, in the example of same figure, in moment t1, the second secondary configuration information issue of version 2 is completed.Visitor is reproduced as a result,
The display layout of component can automatically be switched to based on version 2 by family end 2 by referring to the second secondary configuration information of version 2
The second secondary configuration information layout.
Similarly, in the example of same figure, in moment t2, the second secondary configuration information issue of version 3 is completed.It reproduces as a result,
The display layout of component can automatically be switched to based on version by client 2 by referring to the second secondary configuration information of version 3
The layout of the secondary configuration information of the second of 3.
《Program request issue is used in combination》
It if program request issue can be carried out to configuration information, is issued by and with program request, composition letter can be further improved
The efficiency of transmission of breath.Here, the example that program request issue is carried out to configuration information is illustrated based on Figure 10.
Figure 10 is the figure for illustrating to carry out configuration information the example of program request issue, represents that the issue of configuration information is determined with (a) is schemed
When an example, with scheme (b) represent configuration information data example.In addition, in same figure (a), also with the example of Figure 16 (a), Fig. 3, Fig. 6
In the same manner, one-component, a configuration information are expressed as a block, the block of dotted line represents the component arbitrarily used.In addition, into
It is also identical with the example of Figure 16 (a), Fig. 3, Fig. 6 for the component of issue object.
In the example of Figure 10 (a), in the issue start time of the component of c1 to c4, by main composition with these components together
Information and secondary configuration information are issued with agreement as protocolA.Also, during the issue of the component in the c1 to c4,
The secondary configuration information of version 1 can also be obtained by HTTP with program request.
Similarly, c5 to c8 component issue start time, these components and main configuration information and secondary form are believed
Breath is multiplexed, and is issued with agreement as protocolA.Also, during the issue of the component in the c5 to c8, moreover it is possible to
Enough secondary configuration informations by version 2 is obtained by HTTP with program request.
In order to carry out the acquisition based on such program request, configuration information of the use example as shown in figure (b).Together
Scheming the configuration information of (b) includes secondary configuration information, the secondary configuration information of version 2 of main configuration information and version 1.Further, since
Secondary configuration information (version 1 and 2) is identical with the example of Fig. 2, so omitting the description here.
In the main configuration information of Figure 10 (b), described in the form of basic URL there are two path ("
protocolA:// .../" and " http://.../").In addition, in ＜ component ＞ labels internal references " sub#s1 ",
＜ compositions ＞ labels internal references " sub#p1 ".
Client 2 is reproduced by referring to these information, can reference object be obtained by protocolA or HTTP
Configuration information.That is, since secondary configuration information is issued with protocolA, institute is so as to by " protocolA://.../"
Basic URL combination represent secondary configuration information " sub#s1 " (or " sub#p1 ") URL and obtain.In addition, it is utilizing
It, can be by " http in the case of HTTP:// .../" basic URL combination represent secondary configuration information " sub#s1 "
The URL of (or " sub#p1 ") and obtain.
In addition, as long as protocolA can issue the agreement of configuration information, it is not particularly limited.In addition, such as make
Illustrated by Fig. 4, configuration information can together be multiplexed with other components and be issued, for example, can utilize to be used for number
It broadcasts and issues AV components, in ARIB (Association of Radio Industries and Business, wireless industrial
And commercial guild) specified in agreement or the regulation in the DVB (Digital Video Broadcasting, digital video broadcasting)
Agreement.
Description form ＞s of the ＜ on outer non-economic URL
In the case of there are the published method of multiple (real-time release and program request issue) configuration informations, according to publisher
Formula, it is necessary to it is multiple be used for reference to this composition information URL, so URL description information content become problem.Therefore, in the system
Middle use " transport protocol:The URL of the form of resource identifier/component identifier # component interior elements identifier of // transmission " is retouched
It states.Therefore, by only describing the different parts of each published method (real-time release and program request are issued) basic respectively
In the form of URL, will only it be made of the part (such as " component identifier # component interior elements identifier ") for not depending on published method
Relative URL describe in href attributes, cut down URL description information content.
Here, the information content for based on Figure 11 supplements the URL of relative URL having been used to describe is cut down.Figure 11 is to represent forming
The figure of the description example of the URL of the information with reference to outside is used in information, is the example that basic URL is omitted with (a) is schemed, it is same to scheme (b)
It is the example by the use of the URL set in host node as basic URL, represents to specify in the form of basic URL substantially with (c) is schemed
The example of URL.
But in order to obtain information from the reference object for carrying out reference in the form of relative URL, it is necessary to supplement the transmission of the component
Agreement, transfer resource identifier.
For example, in the example of Figure 11 (a), in component c1, come in the form of relative URL with reference to " sub#s1 ", but do not retouched
State basic URL (transport protocol, the resource identifier of transmission).
At this point, the basic URL for being judged as component c1 is the multiplex stream for transmitting this composition information, included from the multiplex stream
Information in reference to by " sub#s1 " definite information.
In contrast, in the example of same figure (b), component interior element identifier is only set to c1, as relative URL.At this point,
Href attributes " protocolA is set to the father node belonging to c1://.../sub".Therefore, by combining these information, obtain
It must be used to carry out c1 the URL, " protocolA of outer non-economic://.../sub#s1".I.e., in this embodiment, "
protocolA:// .../sub " generates function as basic URL.
In addition, in the example of same figure (c), with the example of Figure 10 (b) in the same manner, c1's that relative URL describes is upper using
Node description has " protocolA:// .../" and " http:// .../" two basic URL.In this embodiment, combination is passed through "
protocolA:// .../" and " sub#s1 ", can with reference to protocolA come " s1 " part of secondary configuration information for transmitting.
In addition, by combining " http:// .../" and " sub#s1 ", it can be by HTTP come " s1 " part with reference to secondary configuration information.
In this way, the description by being set to use basic URL, the description of " sub#s1 " as the common ground in each agreement will not weigh
It is multiple, the data volume of configuration information entirety can be reduced.
In addition, in the above description, only illustrate for being described with reference to the URL of configuration information, but on reference to from structure
Into the URL descriptions of each component of information reference, identical description method can also be used.
《The example 4 of configuration information》
In above-mentioned, issued without the transmission path of specifically mentioned main configuration information and secondary configuration information, but in connection
Server 1 and the network of client 2 is reproduced in the case of hybrid network etc., from publisher server 1 to reproducing in client 2
The transmission path of appearance can also be issued these by different transmission paths there are in the case of multiple.In this regard, based on figure
12 illustrate.Figure 12 is to illustrate the example for issuing main configuration information and secondary configuration information by different transmission paths
Figure represents an example of the issue timing of configuration information with figure (a), with the data example for scheming (b) expression configuration information.In addition, same
Scheme in (a), it is also identical with the example of Figure 16 (a), Fig. 3, Fig. 6, one-component, a configuration information are represented by a block, dotted line
The component that arbitrarily uses of block expression.In addition, the component also example phase with Figure 16 (a), Fig. 3, Fig. 6, Figure 10 as issue object
Together.
In the example of Figure 12 (a), it is necessary to which component c1, c2, c5 and c6 of reproduction are issued by transmission path A, are passed through
Transmission path A also issues main configuration information.In addition, component c3, c4, c7 and c8 for arbitrarily using transmit road by being different from
The transmission path B of footpath A is issued, and secondary configuration information is also issued in the transmission path B.In this embodiment, the hair of main configuration information
Cloth is necessary, but the issue of secondary configuration information is arbitrary.
Mode in this way is set to for example come the main configuration information issued and secondary configuration information with the letter schemed shown in (b)
Breath.In the main configuration information of same figure (b), have through transmission path A to send out described in ＜ components ＞ labels
Component c1, c2, c5, c6 of cloth, and described as the URL (acquisition target information) of outer non-economic "
protocolA://.../sub#s1"。
In addition, in ＜ compositions ＞ labels, description have and meanwhile reproduce video component c1 and audio component c2 and
It can use in " protocolA:// ... which of component represented in/sub#e1 ".Similarly, description has while again
Show video component c5 and audio component c6 and can use in " protocolA:// ... in the component represented in/sub#e2 "
Which.
On the other hand, in secondary configuration information, description has component c3, c4, c7, the c8 arbitrarily used, to these components point
The id of s1 is matched somebody with somebody.In addition, description has the reproduction that text component c3 or c4 is used in the case where using the component arbitrarily used
Mode is assigned with the playback system id of e1.Similarly, description, which has, uses text in the case where using the component arbitrarily used
The playback system of this component c7 or c8 are assigned with the playback system id of e2.
In this way, the main configuration information of Figure 12 (b) includes the information related with the component issued by transmission path A, close
In the component issued by transmission path B, to be described with reference in the form of.Also, main configuration information is in transmission path A with rule
Fixed time interval repeats to issue.
On the other hand, the secondary configuration information of Figure 12 (b) includes the letter related with the component issued by transmission path B
Breath.Also, secondary configuration information repeats to issue in transmission path B with predetermined time interval.
Therefore, the component that client can will be issued in transmission path A is reproduced, by referring in the same manner in transmission path
The main configuration information issued in A and reproduce.It, can be by referring to transmitting in addition, on the component issued in transmission path B
The secondary configuration information issued in the B of path and used.
In this way, in multiple transmission paths issue component in the case of, preferably segmentation include in a certain transmission path
The configuration information of the related information of the component of issue and including the information related with the component issued in other transmission paths
Configuration information.This is because thus, it is possible to cut down the data volume of each component.
In addition, in Figure 12 (a) (b), instantiate all including the component different from recovery time section (c1~c4 and c5~
C8) the main configuration information of related information and secondary configuration information, but can also be as the example of Fig. 2, Fig. 3, by each reproduction
Period is split.Thereby, it is possible to further cut down the data volume of each configuration information.
In addition, in the main configuration information of Figure 12 (b), description has outer non-economic URL ("
protocolA://.../...").I.e., in this embodiment, it is contemplated that in transmission path B by protocolA and issue component c3,
C4, c7, c8 and secondary configuration information.Therefore, by referring to the URL, can be formed from the data flow of transmission path B with reference to secondary
The desired part of information.
《The example 5 of configuration information》
In the case where there is multiple and different contents 18 to be respectively present corresponding configuration information 17, it is believed that in each structure
A part for the information included into information 17 is common.At this point, by the way that common ground is set to a secondary configuration information, Neng Gouyu
Compared to reduction transmitted data amount when individually issuing each configuration information 17.
Here, the example that the common ground of multiple configuration informations is set to a secondary configuration information is illustrated based on Figure 13.Figure 13
It is the secondary composition for representing two main configuration informations corresponding with 2 kinds of transcribers and being shared in these transcribers
The figure of the data example of information.
In the figure, the first main configuration information (main1), secondary configuration information and the second main configuration information are illustrated
(main2).Wherein, the first main configuration information is the main configuration information towards TV, and the second main configuration information is set towards movement
Standby main configuration information.Also, secondary configuration information corresponds to TV and moves the common component of equipment (here, it is contemplated that such as
Text and picture content as data broadcasting in existing terrestrial digital broadcasting) configuration information.
I.e., here, the TV as transcriber is with reference to the first main configuration information and secondary configuration information, such as reproduces such as
High-resolution AV contents as terrestrial digital broadcasting, in addition, display data is broadcasted.
In addition, mobile equipment the second main configuration information of reference and secondary configuration information as transcriber, such as reproduce
The AV contents of low resolution as existing one-segment (One seg) broadcast, and show the component (phase common with TV
When in data broadcasting).Wherein, since the resolution ratio of the display of mobile equipment is low, so while the text component of display uses
The common component with TV, but use the picture content different from what it is towards TV in the background image that shows of background of text.
In order to realize such reproduction, in the first main configuration information of same figure, retouched in ＜ components ＞ labels
State the component that id is respectively c1, c2.In addition, component passes through " protocolA:// ... the description of/sub#s1 " and by outside join
According to.
In addition, in ＜ compositions ＞ labels, description has while reproduces as the c1 of video component and as sound
The c2 of frequency component and " protocolA can be used in the reproduction://.../sub#p1".
On the other hand, in the second main configuration information of same figure, there is id difference described in ＜ components ＞ labels
For the component of c3, c4.In this way, in the second main configuration information, the component for being set to object is different from the first main configuration information.This
Outside, component passes through " protocolA:// ... the description of/sub#s1 " and by outer non-economic, the description and the first main configuration information
It is identical.That is, the first main configuration information and the second main configuration information are " s1 " portions of the identical secondary configuration information of outer non-economic target
Point.
In addition, in ＜ compositions ＞ labels, description has while reproduces as the c3 of video component and as sound
The c4 of frequency component and " protocolA can be used in the reproduction://.../sub#p2".Here, outer non-economic target is "
Sub ", the i.e. secondary configuration information with figure, it is identical with the first main configuration information, but the element variation of reference is p2.
Also, there are the component of c5, c6 and c7 described in the secondary configuration information with figure, these components are assigned with " s1 "
Id.As described above, in the ＜ components ＞ labels of the first and second main configuration information, all by "
protocolA:// ... the description of/sub#s1 " and with reference to the s1 of secondary configuration information.
Therefore, these components become in the TV for using the first main configuration information and use the shifting of the second main configuration information
The component that can be used in dynamic equipment.
In addition, in the case of using optional component in the ＜ par ＞ labels of secondary configuration information, pair show simultaneously
The playback system for being shown as the c5 of the text component and c6 as picture content is assigned with the id of " p1 ".Similarly, use appoint
It anticipates in the case of the component of selection, pair shows that the playback system of the c5 as the text component and c7 as picture content divides simultaneously
The id of " p2 " is matched somebody with somebody.
Therefore, with reference to TV rendering components c1, c2 of the first main configuration information and secondary configuration information (for example, being equivalent to
The video and sound of terrestrial digital broadcasting).It also, can in the case of for example having defined user's operation in these reproductions
Show component c5, c6 (for example, being equivalent to the text of data broadcasting and TV background image) as arbitrary reproduction.
In addition, with reference to mobile equipment rendering components c3, c4 of the second main configuration information and secondary configuration information (for example, phase
When in the video and sound of one-segment broadcast).Also, in the case of for example having defined user's operation in these reproductions, energy
Component c5, the c7 (for example, being equivalent to the text of data broadcasting and movement background image) of enough displays as arbitrary reproduction.
《The other remarks items related with configuration information》
Have in a main configuration information, the situation that the outer non-economic of a secondary configuration information is described with URL by many places.Example
Such as, consider based on main configuration information and secondary configuration information and reproduce client 2 repeatedly reproduced in the reproduction of content it is identical
CM, such as following situation.
■ includes the CM video components for representing CM videos and the CM sound for representing CM sound in the component of constitution content
Component.Also, in secondary configuration information, including each corresponding comp labels with two CM components, further, including being used for
Reproduction client is made to reproduce the par elements of two CM components parallel.In addition, have seq elements described in main configuration information,
The many places description that seq starts between label and seq end-tags is used with reference to the outer non-economic of the par elements of auxiliary structure element
URL。
Seq elements are identically with par elements and excl elements, to be described as the content of compositions elements
Element.Each label (video labels, audio labels etc.) that seq elements are surrounded on the label by and end-tag, table
Showing will first reproduce relatively in the corresponding component of the label that is described compared with upside.In addition, par element representations will with the label by and
The corresponding groups of components of each label that end-tag surrounds should reproduce side by side, and excl element representations will be marked with the label by and end
The corresponding groups of components of each label that label surround should exclusively reproduce.
It in this scenario, can be by the comp labels of script two CM components of expression and for them to be made to reproduce side by side
Par elements situation that multiple secondary configuration informations are described respectively pass through a secondary configuration information and multiple outer non-economic URL
To describe.Number therefore, it is possible to the configuration information sent than further reducing publisher server 1 in the past to reproducing client 2
According to amount.
《Release processing》
Then, the release processing (dissemination method) performed when publisher server 1 issues content 18 is illustrated based on Figure 14
Flow.Figure 14 is the flow chart for an example for representing release processing.In addition, here, first, illustrate that the issue timing in Fig. 3 is issued
The example of the configuration information of Fig. 2 illustrates the processing when using other configuration informations afterwards.
If determining the content of issue object, component transformation component 13 reads the content of issue object from server storage section 11
18, and the component (S1) of issue is transformed to, it is output to issue control unit 16.
In addition, the determining method of issue object content is not particularly limited, such as issue rule at the time of determining in regulation
In the case of fixed content, as long as issue object will be set to corresponding to the content at moment.In addition, it can also will such as pass through
The content specified for the user's operation of publisher server 1 is set to issue object.
If in addition, determining the content of issue object, configuration information analysis portion 14 reads and sends out from server storage section 11
The 18 corresponding configuration information 17 (S2) of content of cloth object.Also, configuration information 17 is analyzed, decision is set to main and forms letter
The information (S3) of breath, and determine to be set to the information (S4) of secondary configuration information.Also, configuration information analysis portion 14 is in configuration information
In the information included in 17, determine that the information described in secondary configuration information notifies configuration information generating unit 15.
Specifically, in the information that configuration information analysis portion 14 includes in configuration information 17, determine to represent in ＜
Reproduction side of the information and expression of component described in components ＞ labels described in ＜ compositions ＞ labels
The information of formula is set to secondary configuration information.Also, it determines the information beyond these being set to main configuration information.
Then, configuration information generating unit 15 generates main form and believes according to the above-mentioned notice from configuration information analysis portion 14
Breath and secondary configuration information (S5, configuration information generation step).
Specifically, in information of the configuration information generating unit 15 described in configuration information 17, will determine to form letter in pair
Information described in breath is rewritten as the form with reference to the pair configuration information, generates main configuration information.In addition, on being determined as in pair
Information described in configuration information, and from main configuration information so as to the identification information (id) that the mode of reference is distributed describes together
In secondary configuration information.
In addition, on the information being determined as described in secondary configuration information, configuration information 17 is carried out according to the issue moment
Analysis describes when generating change every time in the content as the secondary configuration information of new version.In addition, even if changed content is
Determine a part for the information described in secondary configuration information, it is that generation describes decision described in secondary configuration information to be preferably also
Information whole secondary configuration information structure.By being set to such structure, even if the reasons why because of temporary network failure etc.
And the secondary configuration information of a part is not issued to reproducing client 2, by the secondary configuration information received after trouble shooting,
It can continue to normally reproduce.
By such as above processing, from the main configuration information as shown in Figure 2 of the configuration information generation shown in Figure 16 (b) and version

Specifically, issue control unit 16 and the first time of main configuration information is issued what is be periodically determined as and initially reproduce
The reproduction start time of component it is identical or its before.Also, the issue of later main configuration information timing is determined as from the
Once issue timing after the stipulated time or reproduce component the changed timing of structure (with reference to Fig. 3 t3).
In addition, on higher than main configuration information because imagining update frequency when the specific component of expression and its playback system
Issue timing is set to the time interval shorter than main configuration information so that with the frequency higher than main configuration information by secondary configuration information
To issue.Also, the timing that the structure that the timing for changing the version of secondary configuration information is set to the component for making reproduction changes is (with reference to figure
3 t3).
Similarly, issue timing is set to than master by the secondary configuration information lower than main configuration information on update frequency is imagined
The time interval of configuration information length so that issued with the frequency lower than main configuration information.In addition, change the version of secondary configuration information
This timing is set to the timing that the structure for the component for making reproduction changes.As for setting the benchmark of update frequency, in addition,
Also enumerate each component importance, for example comprising component reproduction be necessary or arbitrary such point.Letter is formed main
In the case that breath includes the component that must reproduce, issued with high frequency.On the other hand, it is being to only include arbitrarily reproduction (to permit
Perhaps do not reproduce) component secondary configuration information in the case of, the frequency of issue is set as low.
Finally, control unit 16 is issued by the issuing time table that determines as described above, it is right via server communication portion 12
It reproduces client 2 and issues component and configuration information (main configuration information, secondary configuration information) (S7, issue rate-determining steps), as a result,
Release processing terminates.

It discusses to issue together with component.In addition, issue control unit 16 can obtain main structure by the URL described in main configuration information
Into information and secondary configuration information.For example, in the case where the URL of description is not the URL of publisher server 1, represented in the URL
Storage target in upload main configuration information and secondary configuration information.
Release processing ＞s of the ＜ when the configuration information of Figure 12 (b) is issued in the issue timing of Figure 12 (a)
In the case where the configuration information of Figure 12 (b) is issued in the issue timing of Figure 12 (a), in publisher server 1, set
For being issued by the transmission path (transmission path B) different from the transmission path (transmission path A) in server communication portion 12
Communication unit.
At this point, in the S3 and S4 of Figure 14, configuration information analysis portion 14 is by the information related with the component that must be reproduced
It is determined as the information described in main configuration information.In addition, the related information of the component reproduced with random (optional) is determined
It is set to the information described in secondary configuration information.
Also, in S6, issue control unit 16 will be determined as leading to for reproducing the main configuration information for the component that must be reproduced
It crosses and transmits the transmission path (transmission path A) of the component to issue.In addition, it will be formed for reproducing the secondary of the component arbitrarily reproduced
Information is determined as issuing by transmitting the transmission path (transmission path B) of the component.
In addition, the release cycle of main configuration information and secondary configuration information is not particularly limited, it can also be with corresponding point
It measures unrelated and is set to the defined cycle, can also the cycle be changed according to the attribute of component.
In addition, in S3 and S4, configuration information analysis portion 14 can also determine the information related with important component
For the information described in main configuration information, the information related with other components is determined as described in secondary configuration information
Information.Also, in S6, issue control unit 16 will can also be determined as passing through for reproducing the main configuration information of important component
The transmission path (transmission path A) of the component is transmitted to issue, will be determined as reproducing the secondary configuration information of other components
It is issued by transmitting the transmission path (transmission path B) of the component.
Release processing ＞s of the ＜ when issuing the configuration information of Figure 13
In the case of the configuration information of issue Figure 13, by two contents of issue object (in first content and second
Hold) component (S1) of issue is transformed to respectively, obtain configuration information (the first configuration information and the second composition letter of each content
Breath) (S2).
Then, the information that configuration information analysis portion 14 determines to jointly comprise in the configuration information of both sides is set to secondary composition
Other information are set to main configuration information (S3, S4) by information.In addition, in secondary configuration information, except the composition letter in both sides
Beyond the information jointly comprised in breath, can also identically with other examples, including determine reproduced objects component information or
Represent information of playback system of component etc..
Also, in information of the configuration information generating unit 15 described in the configuration information of each content, it will determine to be set to secondary structure
Information into information is rewritten as with reference to form, generation main configuration information (the first ginseng corresponding with the configuration information of each content
According to form configuration information and second with reference to form configuration information).In addition, generation determines to be set to the information conduct of secondary configuration information
Secondary configuration information (S5).At this point, configuration information generating unit 15 is in secondary configuration information, to being total to from two main configuration informations of generation
Information with reference assigns id (" s1 " of Figure 13) common in these three configuration informations.
Finally, two that control unit 16 determines two main configuration informations and a secondary configuration information and issue object are issued
The issuing time table (S6) of content, and (S7) is issued according to the timetable of decision.
It is for example, wide towards the resolution content of TV and such as one-segment as terrestrial digital broadcasting in issue respectively
In the case of the low resolution content for broadcasting such facing mobile apparatus, by it is common in two contents, for example with data it is wide
Broadcast such text component and when the related information of picture content is set to secondary configuration information, it can also will be towards the high score of TV
Resolution content and corresponding main configuration information are multiplexed and repeat to issue.It is equally possible that by facing mobile apparatus
Low resolution content and corresponding main configuration information be multiplexed and repeat issue.In addition, in such as digital broadcasting
Data broadcasting is such, can also be by will be with this in the case of issuing text component and picture content by data slip

《Reproduction processes》
Then, the flow of the reproduction processes performed when reproducing client 2 and reproducing content 18 is illustrated based on Figure 15.Figure 15 is
Represent the flow chart of an example of reproduction processes.In addition, here, first, illustrate Fig. 2's based on the issue timing issue in Fig. 3
Configuration information and the example reproduced, illustrate the processing when using other configuration informations afterwards.
Client communication portion 22 starts the reception (S10) for the content 18 that publisher server 1 is issued, and the content that will be received
18 are stored in reception data store 26.In addition, content 18 as including configuration information flow data as shown in Figure 4 and by
It receives, storage.
If start for receive data store 26 content 18 storage, reproducing control portion 23 be confirmed whether by for
The main configuration information for reproducing the content 18 is stored in client storage part 21 (S11).In addition, main configuration information can also be more
It is common in the content of a species.At this point, as long as content 18 is stored with the main structure used in the reproduction of different other contents
Into information, then can be applied.
Here, in the case where confirming that configuration information 25 is stored in client storage part 21 ("Yes" in S11), reproduce
Control unit 23 determines the reproduction (S12) that the main configuration information included in the configuration information 25 stored is applied to content 18,
And enter the processing of S15.
On the other hand, in the case where confirming that configuration information 25 is not stored in client storage part 21 (in S11
"No"), reproducing control portion 23 confirms whether the main configuration information received is stored in and receives in data store 26 (S13).
If also, confirm that reproducing control portion 23 determines in data store 26 is received in the case of storage ("Yes" in S13)
The fixed reproduction (S14) that the main configuration information received is applied to content 18, and enter the processing of S15.
In S15, reproducing control portion 23 confirms that reproduction starts required main configuration information and whether secondary configuration information connects
It harvests complete.In addition, reproduce start required configuration information whether receive can by referring to determine in S12 or S14
Application main configuration information and judge.
That is, in the main configuration information of Fig. 2, with reference to a secondary configuration information.Therefore, if the secondary of the reference object forms letter
Breath, which is stored in, to be received in data store 26, then can reproduction be started required configuration information is judged as receiving, if not having
There is storage, then can interpolate that not receive.
It is reproduced in S15 and starts ("No" in S15) in the case that required configuration information does not receive, repeat S15
Processing.Wherein, in the case of the main configuration information that different versions is received during S15 is reprocessed, based on this
Main configuration information carries out reproducing the judgement for starting whether required main configuration information and secondary configuration information receive.
In S15, if confirming, reproduction starts required configuration information and receives ("Yes" in S15), reproducing control portion
23, based on main configuration information and secondary configuration information, make reproducing unit 24 start the reproduction (S16) of content 18.
Specifically, reproducing control portion 23 determines to become ginseng in main configuration information in the secondary configuration information of reference object
According to the part of form, the reproduction required information of the content 18 of the combination of component etc. is obtained.Also, pass through the information according to acquisition
And the component and its playback system of reproduced objects are notified reproducing unit 24, it is made to reproduce content 18.
In addition, reproducing control portion 23 confirms the configuration information that new version whether is received in the reproduction of content 18
(S17).In addition, as illustrated by based on Fig. 4, if the configuration information for receiving new version is preferably able to reference to effectively
It loads head and determines.
Here, if the reception ("No" in S17) of the configuration information of new version is not confirmed, into the processing of S19.Separately
On the one hand, in the case where confirming to receive ("Yes" in S17), the configuration information of application is updated to new by reproducing control portion 23
The configuration information (S18) of version.
Specifically, in the case where receiving the main configuration information of new version, instead of being determined in S12 or S14
The main configuration information of application, using the main configuration information of new version.In addition, receiving the secondary configuration information of new version
In the case of, instead of the secondary configuration information of preceding version, using the secondary configuration information of new version.
And then existing control unit 23 judges whether to terminate the reproduction (S19) of content 18, in the case of end (in S19
"Yes"), this meaning is notified reproducing unit 24 to make its end of reproduction, end of reproduction processing.On the other hand, in situation about not terminating
Under ("No" in S19), back to the processing of S17.

《On main configuration information and secondary configuration information》
In the content transmission/reception system 300 in the main configuration information of issue, to components elements, par elements, with
And seq elements impart id attributes.These id attributes are that reproducing control portion 23 ' is used to use secondary configuration information by main configuration information
It is updated to the attribute of configuration information 25 and reference.
In addition, in content transmission/reception system 300 in the secondary configuration information of issue, description has with ref_id attributes
Insert elements.The content of insert elements is appended to attribute by reproducing control portion 23 ' on each insert elements being described
Value is endowed in the element in the main configuration information of the id attributes identical with ref_id attributes.That is, which represents main composition
The position that can be updated and (be inserted into) in information.
For example, reproducing control portion 23 ' is receiving the main configuration information shown in Figure 18 (a) from main publisher server 100, and
In the case of the secondary configuration information received from secondary publisher server 110 shown in Figure 18 (b), following processing is carried out.
The property value of ■ addition id attributes is the comp element of " c3 ", the property value as the id attributes in main configuration information
For the content of the components elements of " cpn1 ".
The property value of ■ addition comp attributes is the text element of " c3 ", the attribute as the id attributes in main configuration information
It is worth the content of the par elements for " par1 ".
As a result, main configuration information is updated to the configuration information 25 as shown in Figure 18 (c) by reproducing control portion 23 '.Also,
In the case that reproducing control portion 23 ' receives the secondary configuration information of Figure 18 (b) before the reproduction of content or in reproducing, with main hair
The component in parallel of cloth server, secondary issue corresponding with the text elements that the property value of comp attributes is " c3 " is reproduced again to be taken
The text component of business device.
Similarly, reproducing control portion 23 ' is receiving the main configuration information shown in Figure 19 (a) from main publisher server 100, and
And in the case of the secondary configuration information received from secondary publisher server 110 shown in Figure 19 (b), carry out following processing.
Two comp elements of the property value of id attributes respectively " c3 " and " c4 " are appended in main configuration information by ■
Id attributes property value for " cpn1 " components elements content end.
The property value that ■ additions include comp attributes is the video elements of " c3 " and the property value of comp attributes is " c4 "
Par element of the audio elements as content, the property value as the id attributes in main configuration information are the seq elements of " seq1 "
Content.
As a result, main configuration information is updated to the configuration information 25 as shown in Figure 19 (c) by reproducing control portion 23 '.It reproduces
In the case that control unit 23 ' receives the secondary configuration information of Figure 19 (b) before the reproduction of content or in reproducing, based on Figure 19
(c) configuration information 25 after the completion of the reproduction of the component of main publisher server, is reproduced side by side as secondary publisher server
Issue component, corresponding with the video elements that the property value of comp attributes is " c3 " video component and the category with comp attributes
Property value be " c4 " the corresponding sound component of audio elements.
In addition, reproducing control portion 23 ' implements to add in the element conduct described in secondary configuration information to main configuration information
In the case of the processing of the content of seq elements, it is necessary to the end of the additional content that seq elements are come for additional element.For example,
The main configuration information shown in Figure 20 (a) is being received from main publisher server 100, and figure is received from secondary publisher server 110
In the case of secondary configuration information shown in 20 (b), additional video elements so that the property value of comp attributes is the video of " c3 "
Element comes end of the property value of id attributes for the content of the seq elements of " seq1 ".
Therefore, element, the different pair being added as the content of seq elements is being included from publisher server issue
In the case of configuration information, according to the order for reproducing the secondary configuration information of the reception of client 2 ', the content of configuration information 25 is different.Example
Such as, have the including video elements corresponding with the video component that should first reproduce first secondary configuration information and including with should after reproduce
The corresponding video elements of video component the situation issued successively of the second secondary configuration information.In this case, in the first secondary structure
During into the issuing path difference of the issuing path of information and the second secondary configuration information, client 2 ' is also reproduced sometimes and first receives second
Secondary configuration information.
Also, in the case of formerly receiving the second secondary configuration information, two are added as the content of seq elements
Video elements, but the additional video component with should first reproduce after the corresponding video elements of video component with that should reproduce afterwards
Corresponding video elements.As a result, reproducing control portion 23 ' along the order of the intention of content publisher according to not reproducing
Video component.
Therefore, processing should be updated by preferably including expression in the ci elements of main configuration information and secondary configuration information
The layer attributes of order.For example, it is desirable to main configuration information is set to the configuration information as shown in Figure 21 (a), by what is issued successively
Secondary configuration information is set to the configuration information of Figure 21 (b) and the configuration information of Figure 21 (d).
In the case where the configuration information of issue includes layer attributes, reproducing control portion 23 ' is by the category of layer attributes
Property value be i secondary configuration information be used in ith configuration information 25 update processing.
For example, the main configuration information in the Figure 21 (a) received from main publisher server 100 is recorded in client storage part
In the state of in 21, in the case of the secondary configuration information for first receiving Figure 21 (b), using the secondary configuration information received immediately
The main configuration information of Figure 21 (a) is updated to the configuration information 25 of Figure 21 (c).Also, if the pair of Figure 21 (d) is received after which
The configuration information 25 of Figure 21 (c) is then updated to the structure of Figure 21 (e) thirty years of age by configuration information using the secondary configuration information received
Into information 25.
On the other hand, it is recorded in client in the main configuration information of the Figure 21 (a) received from main publisher server 100 and deposits
In the state of in storage portion 21, in the case of the secondary configuration information for first receiving Figure 21 (d), until carrying out having used layer attributes
Property value for " 1 " secondary configuration information update processing until, which is recorded in client storage part 21.
Also, if the secondary configuration information of Figure 21 (b) is received after which, it has been carried out more using the secondary configuration information of Figure 21 (b) first
On the basis of new processing, processing is updated using the secondary configuration information of Figure 21 (d).
In this way, even if which secondary configuration information reproducing control portion 23 ' first receives, all by the main configuration information of Figure 21 (a)
It is updated to the configuration information 25 of identical Figure 21 (e).Therefore, reproducing client 2 ' must be according to the intention along content publisher
Order reproduce video component.
《The variation 300a of content transmission/reception system 300》
As previously mentioned, content transmission/reception system 300 on the basis of the processing as shown in Figure 22 (a) has been carried out, reproduces

Determine information analysis portion 1014 and including issuing control unit 1016a.Secondary publisher server 110a is different from secondary publisher server 110,
Including issuing control unit 1116a.
Set informations 19 of the reproducing control portion 23a based on issue object content determines that the issue with issue object content has
The publisher server of 1 or more (for example, main publisher server 100a and pair publisher server 110a) of relation, establishment and institute
The connection of definite each publisher server.Also, reproducing control portion 23a asks each publisher server issue issue object content
Configuration information.Reproducing control portion 23a is based on the configuration information issued from each publisher server, from what is issued from each publisher server
In groups of components determine reproduce needed for groups of components, and record determined by groups of components and reproduce.
Control unit 1016a is issued to issue the main configuration information 17a related with issue object content to reproducing client 2a, divide
Measure group 18a and set information 19.If it is related with issue object content from client 2a receptions are reproduced to issue control unit 1116a
Secondary configuration information 17b is then sent to and reproduces client 2a by the request of configuration information.Afterwards, control unit 1116a is issued to reproducing
Client 2a issues the groups of components 18b of issue object content.
If approximately, content transmission/reception system 300a is on the basis of the processing as shown in Figure 22 (b) has been carried out, then
Existing client 2a starts the reproduction of content.
《The remarks item related with content transmission/reception system 300》

From the above description, publisher server 100 ' is by issuing new secondary configuration information in the issue of content
To client 2 ' is reproduced, allow hand over as the component of the reproduced objects in client 2 ' is reproduced.
In addition, as the configuration information of Figure 25, preferably include representing that secondary form is believed in the ci elements of secondary configuration information
The version attributes of the version of breath.Reproduce client 2 ' use secondary configuration information and in the case of having updated configuration information 25,
The secondary configuration information of version (property value of version attributes is relatively small) older than the pair configuration information cannot be used and update composition
Information 25.For example, use the secondary configuration information of Figure 25 (d) and after having updated the configuration information 25 of Figure 25 (a), even if receiving
To the secondary configuration information of Figure 25 (b), which can not be used in the update of configuration information 25.
The secondary configuration information of old version cannot be used and update configuration information 25, just like advantage described below.
For example, it is contemplated that publisher it is expected reproduction client 2 ' is made to reproduce video component 3 and sound point after time tl
Amount 4 makes reproduction client 2 ' reproduce the situation of video component 5 and sound component 6 after moment t2 (＞ t1).At this point, it sets
It is set to the secondary configuration information that publisher server 100 ' issues Figure 25 (b) when as moment t1, figure is issued when as moment t2
The secondary configuration information of 25 (d).
As previously mentioned, the secondary configuration information of the Figure 25 (b) first issued sometimes because network failure when the reasons why due to compare after issue
Figure 25 (d) secondary configuration information after reach and reproduce client 2 ' and (the secondary configuration information of Figure 25 (b) is reached and reproduces client 2 '
At the time of be set to t3 (＞ t2)).Even if client 2 ' at this moment, is reproduced also without using the Figure 25's (b) received in moment t3
Secondary configuration information and update configuration information 25, so the configuration information 25 of client storage part 21 maintenance figure before and after moment t3
The configuration information 25 of 25 (e) and it is constant.Therefore, though reproduce client 2 ' first receive Figure 25 (b) secondary configuration information and
Which of secondary configuration information of Figure 25 (d), reproduced after moment t2 all in accordance with the intention of publisher video component 5 with
And sound component 6.
On the other hand, if in the ci elements of secondary configuration information not include version attributes, reproduce client 2 ' when
The video component 3 of the not intention according to publisher and sound component 4 can be reproduced later by carving t3.
In this way, secondary configuration information ci elements include version attributes have can prevent reproduce client 2 ' into
It is capable not according to the reproduction of the intention of publisher the advantages of.
In addition, on main configuration information, want to make reproduction client in the reproduction of issue object content there is publisher
In the case of the 2 ' components reproduced always, the element related with the component is described in main configuration information.In addition, main configuration information

Configuration information 17a and include in ci elements layer attributes and version attributes both sides attribute secondary configuration information 17b.
At this point, illustrate the update processing for the configuration information 25 for reproducing client 2 ' with reference to Figure 27.
Reproducing control portion 23 ' the version attributes of the secondary configuration information received property value in the case of " 1 ",
Based on the property value of layer attributes, configuration information 25 is updated using the pair configuration information in appropriate timing.For example, it is inciting somebody to action
After the secondary configuration information of Figure 27 (a) is recorded in client storage part 21 as configuration information 25, once also formed without update
In the case of the configuration information that Figure 27 (b) is received in the state of information 25, the configuration information 25 of Figure 27 (a) is updated to immediately
The configuration information 25 of Figure 27 (c).
On the other hand, reproducing control portion 23 ' belongs in the version of the secondary configuration information (object pair configuration information) received
Property property value for " 1 " in addition in the case of, carry out sometimes with the property value of the version attributes of object pair configuration information for "
Different processing when 1 ".
Specifically, object pair configuration information layer attributes property value and the reception in object pair configuration information
Before the property value of the layer attributes of secondary configuration information that is most recently received it is identical, and the version of object pair configuration information belongs to
In the case that the property value of property is larger, the content of insert elements is not appended to configuration information 25, but with insert elements
Content to replace the content of the corresponding element in configuration information 25, (that is, insert is construed to the main structure for Figure 27 (a) always
Into the insertion of information.By the processing from the case that updated configuration information Figure 27 (c) of prime is seen, being construed to displacement pair
Answer the content of element).For example, after the configuration information of Figure 27 (b) is received, the configuration information of Figure 27 (d) is subsequently received
In the case of, the configuration information 25 of Figure 27 (c) is updated to the configuration information 25 of Figure 27 (e) immediately.
